HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters PatentNo. 584,951, dated June 22,1897. Application filed November 21, 1896. Serial No. 612,931. (Nomodel.)

To all whom it may concern.-

Be it known that I, ROBERT MORE, Jr., a citizen of the UnitedStates,residing atBridge-. ton, in the county of Cumberland, in theState of New Jersey, have invented certain new and useful Improvementsin Hydrocarbon- Burners, of which the following is a specifica tion.

My invention aims to provide a hydrocarthat it will uniformly receivethe maximum heat.

In the accompanying drawings, I show and herein Idescribe a good form ofa convenient embodiment of my invention, the particular subject-matterclaimed as novel being hereinafter definitely specified.

In the accompanying drawings,

Figure 1 is a view in sideelevation, partly in section, of a hydrocarbonburner, em bod ying a good form of my invention.

Figure 2 is a sectional elevation of the same, section being supposed onthe dotted line 0cx of Figure 1, and sight being taken in the directionof the arrows applied to said line.

In the accompanying drawings,

A indicates an oil supply tube, controlled by acock or valve a of theusual construction.

B is a steam or compressed airsupply tube controlled by a cook or valveb of the usual construction.

The tubes A and B in the form shown, lead to and are entered in andthreaded with respect to the oppositely facing ports 01 d of a shell orcasting D, the interior of which is by a diaphragm D divided into twochambers d d The oil tube A, as will be observed, opens through the portd into the oil chamber 02 and the steam or air tube B opens through theport 61 into the steam or air chamber d The body of the diaphragm D isshown as in line with the axes of the ports (I d, and is connected tothe body of the shell or casting by two angular extensions 0 c.

E is a burner tube, of considerable diameter, mounted in the wall of thecastingD, and opening into the steam or air chamber d F is an oil tubeof considerably less diameter than the burner tube, supported within andin axial relation to said burner tube, being maintained in such positionby the engagement of its inner end in a suitable opening formed for itin and extending through, the diaphragm D the result of this arrangement being that the inner end of the oil tube F opens into the oilchamber 61 As will be understood, the oil fed through the tube A willpass through the oilchamber (Z and through the oil tube F, and emergefrom the outer end of the latter, while the steam or compressed air fedfrom the pipe B will pass through the steam chamber 61 and through theannular space between the burner tube and-the oil tube, until it reachesthe mouth of the oil tube, at which point it will commingle with the oilemerging therefrom.

As will be observed in Figure 2, the oil tube F extends horizontallythrough the center of the steam or air chamber, so that the enteringvolume of steam or air would tend, in the absence of provision to thecontrary, to divide, with the result that half of the steam or air wouldpass to one side, and the other half to the other side of said tube, andthereupon said steam or air would ascend the burner tube in a directforward movement.

I have found that by imparting to the steam or air a spiral movement asit passes along the burner tube, said steam or air will upon coming tothe mouth of the oil tube very completely sub-divide the oil issuingthererom, and commingle with it, such sub-division and commingling beingvery much more thoroughly accomplished than when the steam or air movesin a straight direction along the burner tube as hereinbefore referredto.

I impart this spiral movement to the steam or air by feeding a greateramount of it Within the chamber d on one side of the oil tube than onthe other, and in the form of my invention shown in the drawingsaccomplish this by forming a channel g of graduated depth in the corneror angle of the diaphragm D facing the entering volume of steam or airand to one side of the oil tube as shown in Figure 2, thus giving saiddiaphragm a partly spiral form.

As will be understood, the major part of the steam or air will enter thechamber (Z in a direction tangential to it, and, as a result of theannular form of the channel through which the steam or air must pass tothe point of combustion, the volume of steam or air thus entering thesteam or air chamber will take on a regular spiral movement.

The burner tube E is, as shown in Figure 1, reduced in diameter in theusual manner, at a point in the vicinity of the mouth of the oil tube,to carry the volume of steam or air into contact with the volume of oilemerging from said oil tube,said reduced portion of the burner tubebeing designated e,--and I provide said tube with an axial extension Gpreferably continuous of said reduced portion, and expanded to form aflaring or trumpet mouth.

In the operation of myhydrocarbon burner, the flame exists as to itsbase within the flaring or trumpet mouth of the burner tube, andproduces a uniform and high heat.

Exactly what influence the trumpet mouth of the burner tube has upon thecombustion taking place in the burner, I am unable to state; the facthowever remains that by the use of this trumpet mouth extension theintensity and uniformity of the heat produced, and the steadiness of theflame and its proximity to the burner are all materially increased.

The proximity of the flame to the burner maintains the oil in the oiltube and in the oil chamber in a heated condition, thus increasing itsfluidity, whereby the clogging of the bore of the oil tube, which isliable to occur where crude oil is used in a cold condition, isprevented, and the efficiency of the burner as a whole increased. Inorder to slightly retard the passage of the oil through the oil chamberand oil tube, and therefore hold it longer subject to the heating actionof the flame of the burner before being used, I prefer to project theinner end of the oil tube slightly beyond the diaphragm, so that whenthe burner is held in a vertical position the oil must before it passesinto the oil pipe and down through the latter, first surmount the endwall of said oil tube.

7i is a lock nut mounted on the oil tube by which the oil tube may befirmly secured in any position of adjustment as will be understood, theoil tube may be adjusted to regulate the size of the passage between itsoutlet end and the inner wall of the burner tube E.

It will of course be understood that the precise form and arrangementshown in the accompanying drawings, and herein described constitutessimply the preferred embodiment of my invention, and that numerousmodifications of mechanical construction may be made without departingfrom the spirit of my invention.

Having thus described my invention, I claim 1. In combination with thesteam or air and oil supply pipes, a shell or casting into which saidpipes discharge, a diaphragm extending through said shell or casting,said diaphragm serving to divide the interior of the casting into twochambers, aburner tube leading from one of said chambers, an oil tubemounted within said burner tube, and leading from the other of saidchambers, said diaphragm being so formed or arranged that it exists infront of the mouth of the air or steam tube, and is as to part of itsstructure of spiral form, so as to impart spiral motion to the steam orair, substantially as set forth.

2. In combination with the steam or air and oil supply pipes, a shell orcasting into which said pipes discharge, a diaphragm extending throughsaid shell or casting and permanently connected to it, said diaphragmserving to divide the interior of the casting into two chambers, aburner tube leading from one of said chambers, an oil tube mountedwithin and concentric with respect to said burner tube, leading from theother of said chambers, and a channel or groove formed in the diaphragmat one side of the oil tube and in front of the steam or air supplypipe, substantially as set forth.

In testimony that I claim the foregoing as my invention I have hereuntosigned my name this 13th day of November, A. D. 1896.
